Patient's question:
My dad's blood pressure is very strange. In the summer, my dad's blood pressure isn't particularly high, and he feels fine, but when winter comes, my dad's blood pressure goes up. Sometimes he even gets dizzy. What's the difference between high blood pressure in winter and summer?Doctor's answer:
Human blood pressure is affected by seasons and temperature. In winter, blood pressure tends to decrease overall. Because the weather is cold in winter, the blood vessels in the human skin contract, and sweating increases. The cold affects cause blood vessels to contract, increasing the resistance to blood circulation. As blood flow slows down, renal blood flow relatively rises, and urination increases. It is recommended that patients maintain a light diet and engage in appropriate exercise during treatment.
